Particle A of mass 0.65 kg and a particle B of mass 0.35 kg are attached to ends of a light inextensible string which passes over a fixed smooth pulley. B is held at rest with the string taut and both parts of its vertical. Find the resultant force exerted on the pulley by the string.
(Tension: 4.55N and Gravity = 10m/s)
